Metalorganic deposition (MOD) is a nonvacuum method of thin-film deposition which allows easy alteration of chemical components and is compatible with thin-film processing. We report the preparation of thin-film superconductors by MOD. Rutherford backscattering spectrometry was used to determine film compositions and thicknesses. Films, approximately 500 nm thick, of YBa/sub 2/Cu/sub 4/O/sub z/ (z undetermined) were deposited on <100> single-crystal SrTiO/sub 3/. A superconducting onset temperature of 90 K was measured with 37 K the zero resistance temperature. Scanning electron microscopy revealed grain sizes approximately 250 nm in diameter.
